Clene Nanomedicine Receives Two Patent Notice of Allowances in the U.S. for Its Platform Nanocrystal Therapeutic Technology

IP portfolio now totals over 160 patents issued, allowed, and pending

SALT LAKE CITY, April 30, 2021 (GLOBE NEWSWIRE) — Clene Inc. (NASDAQ: CLNN) (along with its subsidiaries, “Clene”) and its wholly owned subsidiary Clene Nanomedicine, Inc., a clinical-stage biopharmaceutical company dedicated to revolutionizing the treatment of neurodegenerative disease using bioenergetic nanocatalysis, today announced the U.S. Patent and Trademark Office has issued Notices of Allowance for two important patent applications covering device and process claims for its platform technology and advanced stage clean-surfaced nanocrystal therapeutic candidates.

The first allowed application titled “Continuous Methods for Treating Liquids and Manufacturing Certain Constituents (e.g., Nanoparticles) in Liquids, Apparatuses and Nanoparticles and Nanoparticle/Liquid Solution(s) Resulting Therefrom” covers a broad set of device claims pertaining to Clene’s platform electrochemical technology for making solutions and suspensions.

Additionally, very broad process claims for forming nanocrystals (such as gold), in liquids, is covered in the second allowed application titled “Continuous, Semicontinuous and Batch Methods for Treating Liquids and Manufacturing Certain Constituents (e.g., Nanoparticles) in Liquids, Apparatuses and Nanoparticles and Nanoparticle/Liquid Solution(s) and Colloids Resulting Therefrom.”

Both patents, once issued, will continue to provide important intellectual property protection for CNM-Au8, Clene’s lead drug candidate. CNM-Au8 is now being evaluated across seven clinical studies for the treatment of amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and Parkinson’s disease including a Phase 3 registration trial in ALS for which results are expected in the first half of 2022.

“Our leadership position in clean-surfaced nanocrystal therapeutics is fortified by our growing patent estate. These IP assets become increasingly valuable as our clinical pipeline advances, and as CNM-Au8 nears completion of its pivotal Phase 3 trial and potential commercialization,” stated Rob Etherington, President and CEO of Clene.

Clene’s worldwide patent portfolio in the new field of clean-surfaced nanocrystal therapeutics now includes over 130 patents issued and allowed, with around 30 more applications pending. The issued patents cover state of matter claims for suspensions and solutions, as well as processes for making the materials, devices for conducting the unique electro-crystal chemistry processes, and methods of using the novel materials.

About CNM-Au8

Clene’s lead drug candidate, CNM-Au8, a bioenergetic nanocatalyst, is a stable, aqueous suspension of catalytically active gold (Au) nanocrystals. In a patented breakthrough, clean surfaced nanocrystalline CNM-Au8 drives critical cellular bioenergetic reactions in the brain to increase cellular energy, accelerate neurorepair, and improve neuroprotection. CNM-Au8 crosses the blood-brain barrier and is not associated with the toxicities related to synthetic gold compounds or nanoparticles manufactured via synthetic chemistry. CNM-Au8 is currently being evaluated in a Phase 3 registration trial in amyotrophic lateral sclerosis (ALS), a Phase 2 trial examining disease progression via a novel electromyography technique in patients with early ALS, a Phase 2 trial for the treatment of chronic optic neuropathy in patients with stable relapsing multiple sclerosis (MS), and Phase 2 brain target engagement studies in patients with Parkinson’s disease (PD) and MS. CNM-Au8 has demonstrated safety in Phase 1 studies in healthy volunteers and has shown both remyelination and neuroprotective effects in multiple preclinical (animal) models. Preclinical data, both published in peer-reviewed journals and presented at scientific congresses, demonstrate that treatment of neuronal cultures with CNM-Au8 improves survival of neurons, protects neurite networks, decreases intracellular levels of reactive oxygen species and improves mitochondrial capacity in response to cellular stresses induced by multiple disease-relevant neurotoxins. Oral treatment with CNM-Au8 improved functional behaviors in rodent models of ALS, MS, and PD versus vehicle (placebo).

About Clene

Clene, a clinical-stage biopharmaceutical company focused on neurodegenerative disease, is leading the way by using nanotechnology to treat bioenergetic failure, which underlies many neurological diseases. Clene has innovated a novel nanotherapeutic platform to create a new class of drugs—bioenergetic nanocatalysts. Clene’s lead drug candidate, CNM-Au8, is a concentrated nanocrystalline gold (Au) suspension that drives critical cellular bioenergetic reactions in the CNS. CNM-Au8 increases cellular energy to accelerate neurorepair and improve neuroprotection. Currently, CNM-Au8 is being investigated for efficacy and safety in a Phase 3 registration trial for ALS and in Phase 2 trials for multiple sclerosis and Parkinson’s disease. Clene has also advanced into the clinic an aqueous solution of ionic zinc and silver for anti-viral and anti-microbial uses. The company is based in Salt Lake City, Utah with R&D and manufacturing operations in Maryland. For more information, please visit www.clene.com.
